A video blogger tries to create cryptid sightings in order to increase views, but he gets more than he bargained for when his team is massacred by a genuine creature. In other news, kids are preyed upon by a sandworm-like beast, sparking a deadly battle for survival on their own school grounds. As further unknown creature assaults occur, researcher Sousuke Banba is tasked with researching into the mystery. With nothing but the keyword "Kagewani" to lead him, he scours the sites of recent attacks in hopes of finding a lead to eradicating the creatures for good. However, as the pharmaceutical corporation, Sarugaku, begins to intrude on Sousuke's inquiry, he discovers that these risks to mankind are much closer to home.
